Further, various technical terms are used throughout this description. An illustrative resource that fleshes out various aspects of these terms can be found in Newton's Telecom Dictionary by H. Newton, 25th Edition (2009).

Embodiments of the present invention may be embodied as, among other things: a method, system, or set of instructions embodied on one or more computer-readable media. Computer-readable media include both volatile and nonvolatile media, removable and nonremovable media, and contemplates media readable by a database, a switch, and various other network devices. By way of example, and not limitation, computer-readable media include media implemented in any method or technology for storing information. Examples of stored information include computer-useable instructions, data structures, program modules, and other data representations. Media examples include, but are not limited to information-delivery media, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile discs (DVD), holographic media or other optical disc storage, magnetic cassettes, magnetic tape, magnetic disk storage, and other magnetic storage devices. The data on the media can be stored momentarily, temporarily, or permanently.

In some embodiments, systems, methods, and computer-readable media for determining cumulative data usage of a mobile device are provided. In particular, claimed embodiments of the present invention retrieve a data allocation associated with a mobile device and adjust the data allocation based on a communication session of the mobile device. The adjusted data allocation is then stored in association with the mobile device. For example, the adjusted data allocation may be stored at a subscription profile server.

Many mobile device data plans limit the amount of data accessed by the mobile device over a predetermined period of time. Additionally or alternatively, many mobile device voice plans limit the amount of time a mobile device voice plans may limit the amount of time a mobile device may participate in a particular type of call. In both cases, the penalty for exceeding a data usage or call duration limit may comprise additional fees that provide revenue to a network service provider. Accordingly, it is in the best interest for network service providers to have accurate and updated information related to the data usage and/or call duration information associated with a mobile device.

Currently, allocated data usage information associated with a mobile device may be stored at a server, such as a subscription profile server. In particular, allocate data usage information comprises data usage information that is allocated to a mobile device for a period of time. For example, a subscription profile server may store information of data usage that is allocated to mobile devices based on data plans of the mobile devices. For instance, a first mobile device may subscribe to a data plan that allows the mobile device to download 1 gigabyte (GB) of data every month. Accordingly, the allocated data usage of 1 GB/month may be stored at the subscription profile server in association with the first mobile device.

The allocated data usage information associated with the first mobile device may be retrieved in response to a query received at the subscription profile server from a session manager. For instance, the session manager may request allocated data information associated with the first mobile device from a subscription profile server in order to determine the amount of data that the first mobile device may download during a communication session. Further, the session manager may provide a gateway facilitating the communication session with a threshold amount of data usage based on the allocated data usage information received from the subscription profile server. In particular, the threshold amount of data usage provided from the session manager comprises the amount of data that may be transmitted during the communication session before the first mobile device exceeds its allocated data usage for a period of time.

Once the threshold has been set, the gateway may monitor the data usage of the communication session. In one example, the communication session may end before the threshold amount of data has been transmitted. In this example, the gateway may provide the data usage information to the session manager. In particular, the data usage information may comprise the amount of data that was transmitted during the communication session. Alternatively, the data usage information may comprise the amount of data that was downloaded to the first mobile device during the communication session. Once the session manager has received the data usage information from the gateway, the session manager may calculate adjusted allocated data usage information associated with the mobile device. In particular, the session manager may subtract the data usage information of the communication session from the allocated data usage information of the mobile device.

As such, the session manager may calculate adjusted data usage information comprising the cumulative data usage information associated with the mobile device. The session manager may then provide the adjusted data usage information to the subscription profile server. At the subscription profile server, the adjusted data usage information may be stored in association with a profile of the mobile device. In particular, the adjusted data usage information may be stored in an area of the profile of the mobile device that is separate from the area of the profile of the mobile device that stores the allocated data usage information.

In another example, the threshold amount of data may be transmitted during the communication session. The threshold amount of data may comprise the allocated data usage information. In this case, the gateway may inform the session manager that the threshold has been met, and the session manager may instruct the gateway to terminate the communication session.

Alternatively, the threshold amount of data may comprise a percentage of the allocated data usage information. In this alternative case, the gateway may inform the session manager that the threshold has been met, and the session manager may initiate a process of requesting additional funds while the gateway continues to monitor the data transmitted during the communication session.

In either case, the session manager may inform the subscription profile server that mobile device has reached or is about to reach its allocated data usage. Accordingly, the subscription profile server may instruct a web page to request that a user of the mobile device purchase additional data allocation so that the communication session may continue.

receiving, at a subscription profile manager, a request for data usage information associated with a mobile device from a session manager;

providing, at the subscription profile manager, information associated with allocated data usage associated with the mobile device to the session manager;

receiving updated data usage information from the session manager based on data usage information of a communication session between the first mobile device and a second mobile device;

storing the updated data usage information to a profile of the first mobile device at the subscription profile server,

wherein the allocated data usage information is stored in a first portion of the profile of the first mobile device at the subscription profile server, and

wherein the updated data usage information is stored in a second portion of the profile of the first mobile device of the subscription profile server,

receiving, at the subscription profile manager, a notification from the session manager that a threshold associated with the allocated data usage associated with the mobile device has been met;

sending, at the subscription profile manager, a billing request to a billing webpage based on the notification from the session manager that the threshold associated with the allocated data usage associated with the mobile device has been met, the billing request comprising a request that an advertisement to pay for an increased data usage allocation be presented to the mobile device, wherein the increased data usage allocation is data usage that is in addition to the allocated data usage; and

receiving, at the subscription profile manager, adjusted data usage information from the session manager, wherein the adjusted data usage information is calculated by the session manager based on the increased data usage allocation.

11. The media of claim 10, wherein the session manager comprises a policy charging and rules function.

12. The media of claim 10, the method further comprising storing, at the subscription profile manager, the adjusted data usage information at a profile associated with the mobile device.

13. The media of claim 10, wherein the allocated data usage information associated with the first mobile device is provided when there is no updated usage information stored in the profile of the first mobile device.

14. The media of claim 10, wherein the allocated data usage information is stored separately from the updated data usage information.

15. Non-transitory computer-readable storage media (“media”) having computer-executable instructions embodied thereon that, when executed, facilitate a method of determining cumulative data usage information associated with a mobile device, the method comprising:

receiving, at a session manager, a first request from a mobile device to initiate a communication session;

retrieving, at the session manager, data usage information associated with the mobile device from a subscription profile server;

providing, at the session manager, a threshold associated with the data usage information associated with the mobile device to a gateway facilitating the communication session;

receiving, at the session manager, data usage information of the first communication session from the gateway after the communication session has ended;

calculating, at the session manager, updated data usage information associated with the mobile device based on the data usage information of the first communication session;

providing, at the session manager, the updated data usage information to the subscription profile server,

wherein the updated data usage information is stored in a second portion of the profile of the first mobile device of the subscription profile server;

receiving, at the session manager, a second request from a second mobile device to initiate a second communication session;

retrieving, at the session manager, the updated data usage information associated with the first mobile device from the second portion of the profile of the first mobile device of the subscription profile server;

receiving, at the session manager, a first notification from the gateway that the threshold associated with the data usage information has been met;

providing, at the session manager, a second notification to the subscription profile server that the threshold associated with the data usage information has been met,

wherein upon the subscription profile server receiving the second notification, the subscription profile server sends a billing request to a billing webpage requesting that an advertisement for an increased data usage allocation be presented to the mobile device, the increased data usage allocation being data usage that is in addition to the allocated data usage; and

receiving, at the session manager, a third notification from the gateway that the data usage has been increased by the increased data usage allocation.

16. The media of claim 15, further comprising calculating adjusted data usage information based on the increased data usage allocation.

17. The media of claim 16, further comprising sending the adjusted data usage information to the subscription profile manager.

18. The media of claim 17, wherein the adjusted data usage information is stored by the subscription profile manager a profile associated with the mobile device.
